* locale/findlocale.c [NL_CURRENT_INDIRECT] (_nl_C): New variable.
* locale/setlocale.c (setlocale) [NL_CURRENT_INDIRECT]: Null return
from _nl_find_locale ok if for _nl_C_name.
* locale/nl_langinfo.c [NL_CURRENT_INDIRECT]: Use a categories.def
iterator to refer to each category's _nl_current_LC_FOO symbol, so
we know they are all linked in.
